They seem to exercise the hip flexors well without the pounding of excess road miles. I would think they would help your upstroke on the bike as well though the range of motion isn’t nearly as great.
I’m curious because the hip flexors are where I seem to tighten up first on long runs.
fins help ankle flexability, and get the heart rate very high. they can build leg strength, and take pressure off of the shoulders. also, it can make you know what it’s like to go fast (and advantage for sprinters), and how it’s supposed to feel at top speed, etc.
if you want your hip flexors to be more flexible, then committ to stretching them. also, do some deep water running 2 times a month so you’re not overstressing that part of your body. deep water running will give you excellent simulated running benefits without the stress. plus, since the water is supportive, you can do some excersises during that time to help in this area–like pulling knees up high for a few intervals.
for the fins, personally, they really work all of the quad, but I wouldn’t depend on them to resolve the tightness that you’re struggling with. rely on stretching for your solution instead, coupled wiht the DWR to redunce liklihood of injury.
good luck,

Fins can develop the hip flexors quite dramatically. I don’t know if it would translate to improved performance on the bike or not, but it was something that ran through my mind after talking with Frank Day at the IMCDA expo.
